I am\u00a0<\/span>a fisheries ecologist, blending basic and applied. I adopt a holistic perspective that includes all kinds of fishes and interdependent organisms, and considers the roles of humans as components of ecosystems. My overall goal is to contribute to the conservation and management of aquatic ecosystems through teaching, research and outreach.

Research Interests
<\/strong><\/span>I am interested in food webs, lake and reservoir ecology, effects of nonnative species, fisheries management, water quality, contaminant ecology, and effects of climate. <\/span>I apply a wide variety of approaches including field sampling, modeling, field and lab experiments, classical fisheries biology techniques, stable isotopes, eDNA, and otolith microchemistry. My research benefits from collaboration with agencies including Colorado Parks and Wildlife, Wyoming Game and Fish, U.S. Bureau of Reclamation, U.S. Fish and Wildlife Service, Northern Colorado Water Conservancy District, and others.<\/span><\/p>\n
